Hereinafter, the hydrogen water production apparatus according to the present invention will be specifically described.

FIG. 1 is a block diagram showing a typical example of the hydrogen water production apparatus according to the present invention. In the figure, the internal configuration of only the pressure melting tank, which will be described later, is shown as a cross-sectional view.

The hydrogen water production apparatus 100 includes a water supply tank 110 for storing drinking water, a pressurized dissolution tank 120 for mixing water and hydrogen supplied from the water supply tank (water supply tank) 110, and a pressurized dissolution tank 120. It is provided with an electrolysis mechanism 130 that generates hydrogen from a part of the water of the above, and a decompression intake port 140 that takes out hydrogen-dissolved drinking hydrogen water from the pressurized dissolution tank 120 under atmospheric pressure.

The water supply tank 110 is connected to the pressurized dissolution tank 120 via a water supply pipe 111, and a water supply pump 112 and a check valve 113 are attached to the water supply pipe 111. The check valve 113 is configured to be opened only when water is supplied from the water supply tank 110 to the pressurized dissolution tank 120 to prevent backflow from the pressurized dissolution tank 120. If the water supply tank 110 is arranged at a higher position than the pressurized dissolution tank 120, water can flow from the water supply tank into the pressurized dissolution tank 120 by its own weight, and the water supply pump 112 can be omitted. In addition, by using tap water or other pressurized water, water can flow into the pressurized dissolution tank 120 even if the water supply pump 112 is omitted.

The pressure leak valve 121 and the water level sensor 122 are attached to the top of the pressurized dissolution tank 120, and a fine bubble discharge section that discharges hydrogen supplied from the electrolysis mechanism 130, which will be described later, as fine bubbles near the bottom of the pressure leak valve 121. It is equipped with 123. The main body of the pressurized dissolution tank 120 is formed of a material and a thickness capable of withstanding an internal pressure in a predetermined range of being pressurized to atmospheric pressure or higher when producing hydrogen water.

The pressure leak valve 121 is attached to the top of the pressure melting tank 120, and when the pressure in the pressure melting tank 120 exceeds a predetermined value (for example, 0.6 MPa), hydrogen gas staying in the vicinity of the top is discharged to the outside. To do. As a result, it has a function of adjusting the pressure in the pressurized dissolution tank 120 with the above-mentioned predetermined value as an upper limit value. The pressure leak valve 121 may also be used as a depressurizing means controlled to depressurize the inside of the pressurized dissolution tank 120 at a pressure lower than the above-mentioned predetermined value.

The water level sensor 122 is attached to the top of the pressurized dissolution tank 120 and detects whether or not the water level of the water W supplied from the water supply tank 110 to the pressurized dissolution tank 120 has reached a predetermined height. Further, as an example relating to the use of the water level sensor 122, when the water level sensor 122 detects that the water level of the water W has reached a predetermined height, the operation of the water supply pump 112 is stopped to stop the water supply. At this time, a retention space P is formed between the water surface of the water W and the upper surface of the pressure dissolution tank 120 inside the vicinity of the top of the pressure dissolution tank 120.

The fine bubble discharging portion 123 is a member having minute holes such as a mesh body or a porous material on the surface thereof, and is connected to an electrolysis mechanism 130 described later via a hydrogen supply pipe 132. The hydrogen released from the fine bubble discharge unit 123 into the water W in the pressurized dissolution tank 120 is preferably dispersed in water as bubbles (nano bubbles) B having a minute diameter in the nanometer (nm) unit, and is preferably the water W. Hydrogen bubbles B that exceed the saturation amount and are not dissolved in water W are maintained in water W for a longer period of time as they are finer, and eventually rise and are accumulated as hydrogen gas in the retention space P.

The electrolysis mechanism 130 electrolyzes water to generate hydrogen, pressurizes it to a predetermined pressure and sends it out to a hydrogen supply pipe 132, which will be described later. For example, a solid polymer membrane (PEM) method is used. A known device can be applied. Here, the solid polymer membrane is a hydrogen generating membrane having a reverse pressure resistance equal to or higher than the pressure required for pressurizing and supplying hydrogen gas. That is, the upper limit of the pressure at which hydrogen gas can be supplied is set to a value equal to or less than the reverse pressure resistance of the solid polymer membrane. According to this, it is possible to obtain a pressure equal to or less than the reverse pressure resistance as a predetermined pressure relatively easily. The electrolysis mechanism 130 is connected to the pressurized dissolution tank 120 via an intake pipe 131, and takes in water in the pressurized dissolution tank 120 and electrolyzes it to generate hydrogen. At this time, the intake pipe 131 may be provided with an ion exchange means (not shown). The predetermined value to be opened by the pressure leak valve 121 may be set according to the reverse pressure resistance of the solid polymer membrane to protect the solid polymer membrane.

On the other hand, as described above, the electrolysis mechanism 130 is connected to the fine bubble discharge unit 123 via the hydrogen supply pipe 132, and the hydrogen generated by the electrolysis mechanism 130 is being driven by the electrolysis mechanism 130. , It is continuously supplied to the fine bubble discharging unit 123 at a predetermined pressure. That is, the electrolysis mechanism 130 is provided as a part of the hydrogen supply mechanism that supplies hydrogen gas to the inside of the pressurized dissolution tank 120. Further, the hydrogen supply pipe 132 is provided with a pressure sensor 133 for measuring the pressure inside the pipe, and based on the detected value of the pressure sensor 133, hydrogen is stably discharged from the electrolysis mechanism 130 by a control unit (not shown). It is configured so that it is determined whether or not the pressure is supplied, and when the detected value exceeds a predetermined threshold value, the drive of the electrolysis mechanism 130 is stopped so as not to exceed the predetermined pressure described above. Oxygen generated by electrolysis in the electrolysis mechanism 130 is discharged to the outside of the hydrogen water production apparatus 100 from a discharge port (not shown).

The decompression intake port 140 is connected to the lower part of the pressurized dissolution tank 120 via an intake pipe 141. Further, an opening / closing mechanism 142 such as a solenoid valve is attached to the water intake pipe 141, thereby forming a water intake mechanism for discharging water to the outside of the pressurized dissolution tank 120. In the hydrogen water production apparatus 100, the intake pipe 141 has a shape that gradually reduces in diameter from the pressurized dissolution tank 120 toward the decompression intake port 140, thereby stabilizing the flow of hydrogen water through the intake pipe 141. It is possible to maintain a state in which a large amount of hydrogen is contained in hydrogen water. That is, the intake pipe 141 has a shape that suppresses the discharge of water from the decompression intake port 140, so that the pressure of the passing water is the same as the external pressure (atmospheric pressure in this case) at the decompression intake port 140. The pressure is gradually reduced so as to prevent a sudden pressure change of hydrogen water and suppress the gasification of dissolved hydrogen. In particular, in the pressurized dissolution tank 120, hydrogen is dissolved in an equilibrium state by being pressurized to an atmospheric pressure or higher, and hydrogen water taken out at atmospheric pressure after being depressurized can have a high concentration. The extracted hydrogen water can also be supplied to a water server or the like.

2 and 3 are schematic views showing an example of the operation of the hydrogen water production method using the hydrogen water production apparatus 100.

In such a hydrogen water production method, first, as shown in FIG. 2A, water W is supplied from the water supply tank 110 to the pressurized dissolution tank 120. At this time, the drive of the electrolysis mechanism 130 is stopped, and the opening / closing mechanism 142 communicating with the decompression intake port 140 is in a closed state.

Subsequently, as shown in FIG. 2B, when the water level sensor 122 detects that the water level in the pressurized dissolution tank 120 has reached a predetermined height, a control unit (not shown) detects that the water is supplied from the water supply tank 110. Stop (water supply process). In such a water supply step, when the water level of the water W in the pressurized dissolution tank 120 rises, the air existing in the pressurized dissolution tank 120 in an empty state is compressed and the pressure rises. At this time, the excess air may be discharged from the pressure leak valve 121, but in the subsequent step, the pressure leak valve 1 is closed and the pressurized dissolution tank 120 is set as a closed space.

Subsequently, as shown in FIG. 3A, the electrolysis mechanism 130 (see FIG. 1) is driven. That is, water in the pressurized dissolution tank 120 is taken in from the intake pipe 131, and after this is electrolyzed to generate hydrogen, the hydrogen is sent out from the hydrogen supply pipe 132 at a predetermined pressure (for example, 0.2 MPa). Fine hydrogen bubbles (nano bubbles) B are released from the fine bubble discharge unit 123 into the pressurized dissolution tank 120. The pressure in the pressurized dissolution tank 120 is used for water supply from the intake pipe 131 to the electrolysis mechanism 130. Such pressure is obtained by supplying hydrogen, but before hydrogen is generated, an increase in pressure due to water supply to the pressurized dissolution tank 120 described above can also be used. When the bubbles B are further released, a part of the bubbles B is dispersed in the water W as it is, and the remaining bubbles B float and accumulate in the retention space P formed in the upper part of the pressure melting tank 120. Will be done. At this time, the internal pressure of the closed space of the pressurized dissolution tank 120 is gradually increased while maintaining the pressurized state.

Then, the partial pressure of the hydrogen gas accumulated in the retention space P increases, so that the amount of hydrogen exceeding the hydrogen dissolution limit at atmospheric pressure can be dissolved in water, and the water in the pressurized dissolution tank 120 can be dissolved. The hydrogen content increases with the fine bubbles B dispersed and contained in W. At this time, when the supply of hydrogen becomes excessive and the pressure in the pressurized dissolution tank 120 exceeds a predetermined value (for example, 0.6 MPa), the hydrogen gas staying in the retention space P is sent to the outside from the pressure leak valve 121. By discharging, the pressure is adjusted so as to be equal to or lower than the above-mentioned predetermined value (bubble release step). Further, due to the increase in pressure in the pressurized dissolution tank 120, the water W is supplied to the electrolysis mechanism 130 via the intake pipe 131 without using a water supply means such as a pump.

For example, the above-mentioned predetermined value pressure in the pressurized dissolution tank 120 is set as a pressure capable of efficiently dissolving hydrogen in water, and it is appropriate when the pressure leak valve 121 discharges hydrogen gas by a control unit (not shown). It may be determined that the production of hydrogen water has been completed, and the supply of hydrogen from the electrolysis mechanism 130 may be stopped. Further, as described above, the drive of the electrolysis mechanism 130 is also stopped when the pressure value in the hydrogen supply pipe 132 detected by the pressure sensor 133 exceeds a predetermined threshold value. As a result, the amount of hydrogen gas produced can be reliably limited, and the inside of the pressurized dissolution tank 120 is not excessively pressurized.

Subsequently, as shown in FIG. 3B, the opening / closing mechanism 142 is opened to take out hydrogen water from the decompression intake port 140. At this time, since the intake pipe 141 connected to the decompression intake port 140 is arranged at the lower part of the pressurized dissolution tank 120, when the opening / closing mechanism 142 is opened, the internal pressure in the pressurized dissolution tank 120 which is a closed space and Due to its own weight, hydrogen water flows out from the decompression intake port 140. As a result, hydrogen water can be taken out from the decompression intake port 140 under atmospheric pressure without using a water supply means such as a pump. Then, when the water level of the water W in the pressurized dissolution tank 120 drops to some extent due to the outflow of hydrogen water, the process returns to the water supply step shown in FIG. 2A, and water is supplied from the water supply tank 110 into the pressurized dissolution tank 120 again. 2 (b), FIG. 3 (a), and FIG. 3 (b) are repeated.

With the above configuration, according to the hydrogen water production apparatus and the hydrogen water production method, after the water W is stored in the pressurized dissolution tank 120, the hydrogen generated by the electrolysis mechanism 130 is released into fine bubbles. By releasing it into water as fine bubbles (nano bubbles) B from the part 123, the pressure in the pressurized dissolution tank 120 is increased and the dissolution limit of hydrogen in water is increased to dissolve more hydrogen in water. Can be done.

Then, by increasing the pressure in the pressurized dissolution tank 120 with the pressure of hydrogen supplied from the electrolysis mechanism 130, the gas release means for pressurizing the hydrogen used in the conventional hydrogen water production apparatus and releasing it into water. Since (compressor, etc.) is not required, quietness during hydrogen water production can be ensured. Further, since the configuration of such a gas discharge means is not required, the cost of the hydrogen water production apparatus as a whole can be reduced. If a predetermined height of the water level is set lower than the height at which the pressure leak valve 121 is installed, the gas can be stably discharged without contacting the pressure leak valve 121 with water. Can also ensure quietness.

Further, if the water supply tank 110 can be installed at a high place or tap water can be used to supply water having a predetermined pressure, the water supply pump 112 can also be unnecessary.

FIG. 4 is a block diagram showing a modified example of the hydrogen water production apparatus according to the present invention. In the figure, the components common to the components of the hydrogen water production apparatus 100 shown in FIG. 1 are designated by the same reference numerals, and the description thereof will be omitted again.

As shown in FIG. 4, in the hydrogen water production apparatus 100', a retention chamber 120b is additionally formed on the upper surface 120a of the pressurized dissolution tank 120. A pressure leak valve 121 is attached to the retention chamber 120b, and a water level sensor 122 is attached to the upper surface 120a of the pressurized dissolution tank 120.

With such a configuration, water can be supplied up to the upper surface 120a of the pressurized dissolution tank 120 in the water supply process, and the necessary retention space P can be secured above the upper surface 120a, so that a larger amount of hydrogen water can be produced at one time. It becomes possible to do. Further, since the pressure leak valve 121 can be arranged at a position higher than the upper limit of the water level detected by the water level sensor 122, the pressure leak valve 121 does not come into contact with water, and the release of air or hydrogen gas can be stabilized. .. Further, hydrogen water from the decompression intake port 140 may be further guided to the front of the water supply pump 112 to be circulated.

The water intake pipe 141 does not have a shape that gradually reduces in diameter toward the decompression intake port 140 as described above, but may have a shape that has a constant diameter. In this case, the shape is small and long so as to suppress the discharge from the decompression intake port 140. Although it depends on the pressure difference between the inside and the outside of the pressurized dissolution tank 120, for example, the inner diameter of the intake pipe 141 is preferably 1.0 to 5.0 mm, and the length is preferably 1 m or more. That is, by reducing the inner diameter of the intake pipe 141, the pressure loss due to the viscosity of water can be increased, and by increasing the length, the pressure difference due to the pressure loss can be increased, and the passing water can be gradually depressurized. it can. As a result, hydrogen water can be taken out while maintaining a state containing more hydrogen.

In the above, an example in which hydrogen is used as a gas is shown, but it is also possible to dissolve another gas. For example, oxygen may be dissolved in water by supplying oxygen generated by the electrolysis mechanism 130 to the pressurized dissolution tank 120. Further, by providing a heating means such as a heater in the water supply tank 110 or the pressurized dissolution tank 120, the temperature of water can be raised and hydrogen can be dissolved. As a result, hydrogen water can be used for showering, bathing, and the like. Further, other beverages such as tea and coffee may be used instead of the above-mentioned water. In this case, it is preferable to supply the electrolysis mechanism 130 with water obtained by purifying the beverage in the pressurized dissolution tank 120 by a purification device such as an RO device using a reverse osmosis membrane.

FIG. 5 is a block diagram showing another modification of the hydrogen water production apparatus according to the present invention. In the figure, the components common to the components of the hydrogen water production apparatus 100 shown in FIG. 1 are designated by the same reference numerals, and the description thereof will be omitted again.

As shown in FIG. 5, the hydrogen water production apparatus 100 ″ can exchange water and hydrogen water with the water server 150. The water storage tank 151 of the water server is used as a water supply tank instead of the water supply tank 110 described above, and is connected to the pressurized dissolution tank 120 via the water supply pipe 111. Further, the water pipe 141'is extended from the vicinity of the bottom of the pressurized dissolution tank 120 via the opening / closing mechanism 142, and the decompression intake port 140 is connected to the water storage tank 151. As a result, water can be supplied from the water storage tank 151 to the pressurized dissolution tank 120, and the produced hydrogen water can be sent to the water storage tank 151. The decompression intake port 140 does not have to be directly connected to the water storage tank 151, and may be directed so that the discharged water can be supplied to the water storage tank 151.

Here, if the water storage tank 151 is arranged at a higher position than the pressurized dissolution tank 120, water or hydrogen water can flow into the pressurized dissolution tank 120 by its own weight. That is, the water supply pump 112 can be omitted. Further, since water is discharged by the internal pressure of the closed space of the pressurized dissolution tank 120, water is sent from the pressurized dissolution tank 120 to the water storage tank 151 arranged at a high place via the water pipe 141'even if the pump is omitted. can do.

By doing so, for example, hydrogen water can be circulated between the pressurized dissolution tank 120 and the water storage tank 151, and the hydrogen content of the hydrogen water in the water storage tank 151 can be increased and maintained. The hydrogen water thus obtained can be taken out from the faucet 152 of the water server. If the water supply pipe 111 is thickened so that the gas in the pressure dissolution tank 120 can flow back to the water storage tank 151 with respect to the water supply to the pressure dissolution tank 120, the pressure leak valve 121 can be made. Even if omitted, the pressure inside the pressurized dissolution tank 120 can be reduced during water supply.

Although the examples according to the present invention and the modifications based on the present invention have been described above, the present invention is not necessarily limited to this, and those skilled in the art deviate from the gist of the present invention or the appended claims. Without doing so, various alternative and modified examples could be found.
